The whole grand opening show excluding the finale can (and looks like it was) shot directly off of the FJ building. The show was mostly made up of mines and comets, which are generally considered safe are able to be closer to the audience compared to the big high level shells that are used during the finale.
I was expecting for the roof top pyro to be in the lightly show, and not the high level. My guess is the only reason we didn't get the fireworks in the nightly show was budget. Mines and comets do not produce loud noises at all.
